This 22 failure may result from the contrasting results of base flow studies conducted on the amount of streamflow into the 23 Colorado River sourced from groundwater. Some studies rule out the significance of groundwater contribution, while 24 other studies show groundwater contributing the majority flow to the river. This study uses new and extant 1 25 instrumented data (not indirect methods) to quantify the base flow contribution to surface flow and highlight the 26 overlooked, substantial portion of groundwater. Ten remote sub-basins of the Colorado Plateau in southern Utah and 27 northern Arizona were examined in detail. -
Paria Canyon Vermilion Cliffs Wilderness Management Plan
01\16• ,.J ~ UNITED STATES DEPARTMENT OF THE INTERIOR -- BUREAU OF LAND MANAGEMENT ~Lf 1.,.J/ t'CI/C w~P 0 ARIZONA STRIP FIELD OFFICE/KANAB RESOURCE AREA PARIA CANYONNERMILION CLIFFS WILDERNESS MANAGEMENT PLAN AMENDMENT ENVIRONMENTAL ASSESSMENT EA-AZ-01 0-97-16 I. INTRODUCTION The Paria Canyon - Vermilion Cliffs Wilderness Area contains 112,500 acres (92,500 acres in Coconino County, Arizona and 20,000 acres in Kane County, Utah) of public lands managed by the Bureau of Land Management. The area is approximately 10 to 30 miles west of Page, Arizona. Included are 35 miles of the Paria river Canyon, 15 miles of the Buckskin Gulch, Coyote Buttes, and the Vermilion Cliffs from Lee's Ferry to House Rock Valley (Map 1). The Paria Canyon, Buckskin Gulch, Wire Pass, and the Coyote Buttes Special Management Area are part of the larger Paria Canyon-Vermilion Cliffs Wilderness, designated in August 1984 (Map 2). Existing management plan guidance is to protect primitive, natural conditions and the many outstanding opportunities for hiking, backpacking, photographing, or viewing in the seven different highly scenic geologic formations from which the canyons and buttes are carved. Visitor use in Paria Canyon, Buckskin Gulch, and Coyote Buttes has increased from 2,400 visits in Fiscal Year (FY) 1986 to nearly 10,000 visits in FY96-a 375% increase in use over 10 years. This increased use, combined with the narrow nature of the canyons, small camping terraces, and changing visitor use patterns, is impacting the wilderness character of these areas. Human waste, overcrowding, and public safety have become important issues. -

Chapter 3 – Affected Environment
Glen Canyon Dam Long-Term Experimental and Management Plan October 2016 Final Environmental Impact Statement 3 AFFECTED ENVIRONMENT Chapter 3 describes the environmental resources (physical, biological, cultural, recreational, and socioeconomic) that could be affected by the range of alternatives for implementing the Glen Canyon Dam Long-Term Experimental and Management Plan (LTEMP), as described in Chapters 1 and 2. The extent to which each specific resource may be affected by each alternative is discussed in Chapter 4, Environmental Consequences.1 3.1 PROJECT AREA The project area includes the area potentially affected by implementation of the LTEMP (including normal management and experimental operations of Glen Canyon Dam and non-flow actions). This area includes Lake Powell, Glen Canyon Dam, and the river downstream to Lake Mead (Figure 3.1-1). More specifically, the scope primarily encompasses the Colorado River Ecosystem, which includes the Colorado River mainstream corridor and interacting resources in associated riparian and terrace zones, located primarily from the forebay of Glen Canyon Dam to the western boundary of Grand Canyon National Park (GCNP). It includes the area where dam operations impact physical, biological, recreational, cultural, and other resources. This section of the river runs through Glen, Marble, and Grand Canyons in Coconino and Mohave Counties in northwestern Arizona. Although this EIS focuses primarily on the Colorado River Ecosystem, the affected area varies by resources and extends outside of the immediate river corridor for some resources and cumulative impacts. Portions of Glen Canyon National Recreation Area (GCNRA), GCNP, and Lake Mead National Recreation Area (LMNRA) outside the Colorado River Ecosystem are also included in the affected region for certain resources due to the potential effects of LTEMP operations. -
Trout in the Grand Canyon
Trout in the Grand Canyon by David Epstein The tailwater section of the Colorado River below Glen Canyon Dam (GCD) is managed as a blue-ribbon trout fishery. While this tailwater section provides cold, clear water that is ideal for trout success, conditions below Lee’s Ferry are much less suitable for trout (Epstein, this volume, 2005). However, trout have been documented in the river all the way down to Lake Mead. Many accounts from researchers and river guides include the obvious presence of trout in the mainstem river. In fact, trout have been known to congregate at frequently used camp sites in search of human food discarded into the river. Although river conditions seem suitable for trout when the river runs clear, the Grand Canyon does not provide high quality trout habitat, especially when turbidity is high. The majority of the Colorado River in Grand Canyon is high velocity rapids and large eddies, which are not ideal habitat for trout. On the other hand, many of the tributaries to the mainstem provide more traditional riffle, run and pool habitats that are preferentially occupied by trout. Figure 1. Rainbow Trout caught in Kanab Creek close to the mouth (Wilson 2005). During our visit to Grand Canyon the Colorado River was extremely turbid due to sediment-rich inputs from the Little Colorado River. It is not understood how trout adapt to these prolongued periods of turbidity, but we hypothesized that they may find refuge in the warmer, clearwater tributaries. Trout are commonly known to greatly reduce their feeding attempts in highly turbid conditions (Valdez 2005). -

ENVIRONMENTAL ASSESSMENT MIDDLE SALT CREEK CANYON ACCESS PLAN CANYONLANDS NATIONAL PARK, UTAH _______________________________________________________________________ Summary Salt Creek is the largest drainage in the Needles district of Canyonlands National Park. The creek supports one of the most important riparian ecosystems in the park. It is also the heart of the Salt Creek National Register Archeological District, the area with the highest recorded density of archeological sites in the park. A tributary canyon contains the spectacular Angel Arch, a well-known geologic formation that for many years has been a destination point for park visitors. In 1998 the U.S. District Court for the State of Utah ruled, in a lawsuit filed by the Southern Utah Wilderness Alliance, that the National Park Service violated the NPS Organic Act (16 U.S.C. -
Grand Canyon National Park: Kanab Creek, May 2016
Grand Canyon National Park: Kanab Creek, May 2016 Greetings! We just returned from a four night backpack in Grand Canyon National Park - here's our trip report. Day 1 We began our hike at Jumpup Cabin. The road from Jacob Lake was no problem for our passenger car; a few rough spots and a hole behind the cattle grid at the beginning of FR 234 required careful driving, but we encountered no obstacles that would have required high clearance. We started out in the afternoon and hiked down Jumpup Canyon. A trail leads down to Upper Jumpup Spring, and after that we followed the wash. It took us 2.5 hours to cover the 4.5 miles to Lower Jumpup Spring, and a few times we had to seek shelter from rain. We camped on a bench above the wash, a little bit above the spring. From our tent we could see the moon rise above the cliffs. Day 2 The next day began with climbing down the jump-up. A bolt on the ledge above the jump-up makes it easy to belay and lower packs. The climb down the ramp was not as scary as it looked from above, and the rickety looking ladder is actu- ally quite stable. We followed Jumpup Canyon downstream, over beautiful slick rock steps with many little pour offs. The stream vanishes after a while, but there was running water at the mouth of Sowats Canyon—the last water source for the next five hours. Shortly below Kwagunt Hollow, an hour of walking since the jumpup, we entered the limestone slot canyon.
